Can anxiety and panic attacks cause arrhythmias?

Anxiety and panic attacks can indeed trigger and exacerbate arrhythmias due to the body's physiological response to stress. During episodes of anxiety, the body enters a heightened state of arousal, often referred to as the "fight or flight" response. This state is characterized by the release of stress hormones like adrenaline, which can influence heart rate and cardiac conduction.

Increased adrenaline can lead to elevated heart rates and potential irregularities in heart rhythm, making it easier for arrhythmias to occur. The sudden rush of these hormones can affect the electrical system of the heart, leading to conditions such as palpitations, atrial fibrillation, or other arrhythmias.

The influence of anxiety on heart rhythms is not confined to individuals with pre-existing heart conditions; even those without known cardiac issues can experience arrhythmias in response to severe anxiety or panic attacks. This connection highlights the intricate relationship between mental health and cardiovascular health, emphasizing the importance of addressing both physical and psychological well-being in patient care.
